NAD+ research material is supplied to qualified Canadian institutions as a characterized laboratory cofactor for in vitro enzymology, redox-cycling assays, and analytical standards. The compound is the oxidized form of nicotinamide adenine dinucleotide (β-NAD), a dinucleotide central to hydride-transfer reactions.

In vitro, NAD+ accepts electrons from dehydrogenases to form NADH and is a consumed substrate for sirtuins, poly(ADP-ribose) polymerases, and CD38. Experimental designs typically fix NAD+ as a stoichiometric cofactor, a kinetic substrate, or a calibration standard when measuring NAD+-dependent enzymes, PARP activity, or NAD+/NADH ratios in lysates and purified systems. This listing describes cofactor chemistry in experimental systems only.

The material is offered lyophilized. Identity data (CAS 53-84-9, formula C21H27N7O14P2, molecular weight 663.4 g/mol, PubChem CID 5892) are listed on the specification table. The solid is hygroscopic: equilibrate the closed vial to room temperature before opening, store at −20 °C protected from light and moisture, and handle under the receiving institution's chemical-hygiene plan.

Lots are sourced from a GMP-aligned manufacturing partner and released against the stated HPLC purity for that lot (≥98% by HPLC, lot-specific). Identity, chromatographic purity, and related analytical results are documented on the lot certificate of analysis (COA). Retain the COA with the inventory record.

This listing is research-use-only material offered to qualified Canadian institutions for in vitro and laboratory use. Purchasing access is limited to verified Canadian research institutions; individual consumer accounts are not accepted. It is not for human or veterinary use, is not intended for diagnostic procedures, and has not been evaluated or authorized by Health Canada as a drug, diagnostic, or medical product.
